Abstract
Abstract An autonomous radio timepiece is provided which will furnish a usable time display even when it is outside the time zone of the sender or if the timepiece is to be actuated, when it is not possible at a given point in time to receive valid time telegrams. For this, the timepiece is equipped with a manually actuated hour switch for the input of correction information in a supplemental memory, the content of which is summed together for the actual hour display with that of the hour register, possible set by radio. By actuating a START switch to a full hour, for example, synchronized with the reception of an hour synchronizing signal from another source, the content of the register is brought into a full hour position and from there, stepped forward by an internal time keeping step circuit. The receiver is actuated simultaneously in order to correct the content of the register if a valid time telegram is received. Should this not take place within a reasonable period of time, the hour setting, which possibly is displayed incorrectly, may be corrected manually by means of the hour switch, by setting its memory to the display difference required.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
64 words
An autonomous radio controlled timepiece having a time display having an hour display, the timepiece comprising: a receiver for receiving radio time telegrams; a start switch for actuating the receiver and setting the time display to a predetermined initial position; an hour switch for modifying the hour display; and means for initializing an actuation of the receiver responsive to actuation of the hour switch.
Claim 2
Dependent Claim
64 words
An autonomous radio controlled timepiece having a time display having an hour display, the timepiece comprising: a receiver for receiving radio time telegrams; a start switch for actuating the receiver and setting the time display to a predetermined initial position; an hour switch for modifying the hour display; and means for initializing an actuation of the receiver responsive to actuation of the hour switch.
Claim 3
Dependent Claim
59 words
The radio controlled timepiece according to claim 1, further comprising: memory means for storing an hour correction value input by said hour switch; and means for correcting the hour display responsive to the hour switch and comprising a summer for summing a register hour signal received from the receiver and the hour correction value received from the memory means.
Claim 4
Dependent Claim
37 words
The radio controlled timepiece according to claim 1, further comprising an internal stepping circuit, wherein the START switch initiates, upon activation, a time keeping stepping movement of the time display substantially simultaneously from the internal stepping circuit.
Claim 5
Dependent Claim
28 words
The radio controlled timepiece according to claim 3, further comprising means for synchronizing the internal stepping circuit of the receiver with a second cycle of the time telegrams.
Claim 6
Dependent Claim
24 words
The radio controlled timepiece according to claim 1, further comprising an additional display for displaying a manually entered correction value of the hour display.
Claim 7
Dependent Claim
28 words
The radio controlled timepiece according to claim 1, further comprising an electrooptical display comprising a minute display and a second display which may be switched practically without delay.
Claim 8
Dependent Claim
18 words
The radio controlled timepiece according to claim 1, wherein the timepiece is in the form of a wristwatch.
Claim 9
Dependent Claim
33 words
The radio controlled timepiece according to claim 2, further comprising a register for storing received valid time telegrams, wherein the START switch is actuable to reset the register and the hour correction value.
Claim 10
Dependent Claim
26 words
The radio controlled timepiece according to claim 1, wherein means for initializing initializes a temporary actuation of the receiver responsive to actuation of the hour switch.
Claim 11
Dependent Claim
66 words
An autonomous timepiece comprising: a receiver for receiving radio time telegrams; a time display comprising an hour display; a first switch for actuating said receiver and setting said time display to a predetermined initial position; and a second switch for modifying, independently of the radio time telegrams, said hour display; and means for initializing an actuation of the receiver responsive to actuation of the hour switch.
Claim 12
Dependent Claim
66 words
An autonomous timepiece comprising: a receiver for receiving radio time telegrams; a time display comprising an hour display; a first switch for actuating said receiver and setting said time display to a predetermined initial position; and a second switch for modifying, independently of the radio time telegrams, said hour display; and means for initializing an actuation of the receiver responsive to actuation of the hour switch.
Claim 13
Dependent Claim
52 words
The timepiece according to claim 11, further comprising: memory means for storing an hour correction value; and means for correcting the hour display responsive to said second switch and comprising a summer for summing a register hour signal received from the receiver and said hour correction value received from said memory means.
Claim 14
Dependent Claim
43 words
The radio controlled timepiece according to claim 11, further comprising an internal stepping circuit for autonomously keeping correct time of said timepiece, wherein said first switch initiates, upon activation, a time keeping stepping movement of said time display by said internal stepping circuit.
Claim 15
Dependent Claim
28 words
The radio controlled timepiece according to claim 13, further comprising means for synchronizing said internal stepping circuit of the receiver with a second cycle of said time telegrams.
Claim 16
Dependent Claim
23 words
The radio controlled timepiece according to 11, further comprising an additional display for displaying a manually entered correction value of said hour display.
Claim 17
Dependent Claim
23 words
The radio controlled timepiece according to 11, further comprising an additional display for displaying a manually entered correction value of said hour display.
Claim 18
Dependent Claim
21 words
The radio controlled timepiece according to claim 11, further comprising an electrooptical display comprising a minute display and a second display.
Claim 19
